The search for the black energy theory remains elusive as the researchers have found no evidence that the so-called fifth force is acting on an unknown subject.
Researchers from Imperial College London and the University of Nottingham have attempted to test the theory that this fifth force, which according to some scientists, causes the rapid expansion of the universe, acts on matter beyond gravity, electromagnetic and weak and powerful nuclear forces. . But the researchers have found no evidence that the fifth force is hidden by the planets, which makes it difficult to spot.

The fifth force does not cause the deviation of the atom in the experiment
In an experiment published in Letters of physical examination, scientists led by a professor Ed Copeland, of the Center for Astronomy and Particle Physics at the University of Nottingham, has tested the theories of dark energy that claim that the fifth force is weakest when there is has more matter around. This is the opposite of gravity.
Scientists tested the theory by comparing a larger weight to a lower weight, placing it in a vacuum chamber, and then using an atom interferometer to determine if there were additional forces that could be the fifth force. The researchers placed a small metal sphere in the vacuum chamber. The atom could fall inside the chamber and if the theory was true, it would change slightly when it would pass to the sphere, thus changing the path of the atom in free fall. But scientists have not been able to find the strength.
"This experiment, which links atomic physics with cosmology, has allowed us to eliminate a wide range of proposed models for explaining the nature of dark energy, and will allow us to constrain many other models of physics." 39, black energy, "said Copeland in a statement. press release announcing the results of the experiment. "It's very exciting to be able to discover something about the evolution of the universe using a table experience in a basement of London."
Scientists agree that the universe is expanding, but they do not know the cause
The universe is growing at a rate that is accelerating, but scientists have not been able to find the answer to its cause. They seem to agree that it is a form of energy that works in the opposite of gravity. The experience of the researchers does not mean that the fifth force does not exist. Further research is needed to determine what lies behind the so-called fifth force.
